Georadar anisotropy in the Gotthard Gneiss, Switzerland [PDF]
Geophysical Research Letters, 1997 Georadar data recorded in a crystalline gneiss of southern Switzerland exhibit two effects that are related to anistropic metamorphic fabric. In the first, signal coherence appears to be better for waves propagating parallel to the direction of foliation and, in the second, rms velocities of waves propagating along the foliation are higher than for ...

Kirchhoff migration method in the problem of detecting hidden metal objects using ultra-wideband GPR
Вісник Харківського національногоуніверситету імені В.Н. Каразіна. Серія: Радіофізика та електронікаBackground: Ultra-wideband (UWB) GPR systems are widely used to detect hidden objects. However, efficient data processing, especially in complex environments with heterogeneities, remains a pressing problem.

Georadar-Wellengeschwindigkeiten mit Fehlerrechnung
, 2014 We develop three new approaches for ground penetration wave velocity calcultaions. The first is based on linear moveout spectra to find the optimum ground wave velocity including uncertainties from multi-offset data gathers.
